Symi Location

36.5856, 27.8429

36.58557, 27.84287 View on OpenStreetMap →

Symi sits at 36.5856°N, 27.8429°E, on the coast of Aegean Islands, Greece. The marker on the map shows the spot the readings on this page come from. It usually sits a short distance from the town centre, out on the open water itself, so the numbers stay tied to the coast rather than a generic point inland.

Coastlines bend, headlands focus the water, and the temperature can run noticeably differently between two beaches that look close together on a map. Comparing nearby locations is a quick way to see how local geography is shaping the readings.
